DERAILER.

I ,srnclnlcs'rloiv forming part of Letters Patent No. 728,740, dated May it, 1908. v Application filed August 18, 1902. Serial No. 120,037. (No model) i ToaZlwhom it may concern. I

Be it known that I, Gnonen L. MANSFIELD,

I a citizen of the United States, residing at Chicage, in the. county of Cook and State of Illinois, have invented certain newand useful.

Improvements in Derailers, of which, the following is a specification. 1

My invention relates to derailing-switches andthe object of my invention is to provide I 'ward'and upon it.

a device which is thrown over or across the rail'after cars have been placed on the sid ing' and w-hich will derail the cars if from 'accidental-causesthey start back toward the maimtrackswitch. The devices which have hitherto been designed for this purpose have been moreor'less objectionable because ofv theirweight and'cost, and particularly because of their height above the rail, which causegthem to interfere with apass'ing train, even when thrown ontof operating position.

A particular object of this invention is "to,

provide a derailer whichmay be automat ically aot-uatedfrom the switch or from; the

watch-tower and. which when, moved away from therail-will fall'below the level of the.

rail-head, sotliat'it will be enti rely below the truck-bases of passing cars. Another particnlar'object of the invention is toimprove the construction-0t: derailers with regard to the size and weight thereof with rails ofdifferentheights.

and to standardize thesame for employment 7 My invention consists generally in a derailer provided with a wheeldifting portion and a deflecting rib or shoulderto force the wheel ofi therail andpivoted operating means axially parallel with the rail,-

,My invention further consists in various cdnstructions and 'in combinations of parts,

all asflhereinafter described-and particularly. I

over the head of the rail, after which there is no bending strain upon the plate.

pointed out in the claims.

' The invention will be more readily under stood by reference to the accompanyingdrawings, forming a part of this specificaliomjand in 'which Figure l is a plan view of a derailer embodying my invention; Fig. 2 is an elevation. thereof; the rail and ties-being removed. Fig. 3 is a'transverse vertical section on the line 5 of Figs. 1 and 2 viewed in the direction of the arrow and showing the derailer removed from the rail. Fig. t is a similar sectional view on the line 4* of Figs. 1 and 2, showing the device in derailing position; and Fig. 5 is a vieu like unto Fig. 4:, illustrating the positions of the parts during the first part of thethrow-out movement of the de-' the rail 3 and preferably provided with the overhanging iipor flange 4;. The top of the plate is provided with the wheel or tread lifting blockfi, integral with the plate and-hav-.

ing its end 5" extending beyond the end of the plate 2 and beveled or inclined, as shown at 5" The opposite end of the block 5 tapers ,down to the plate, and the top of the block,

preferably fiat, as shown,is parallel with the top of the rail. The plate 2 is formed with thehigh diagonal deflectingshoulder or rib 6, extendin g from corner to corner of the plate 2 and adapted to be engaged by the flange of the wheel after the wheel has been lifted by the block 5. It will be notedthat the gap or notch '2" at the end of the plate between the block 5am the outer end of the rib 6 is sufficient-ly deep to prevent the striking of the wheel-flange upon the end of the plate when the wheel first rolls upon the block'5. In this way the plate is relieved from pressure at a point overlying the flange of the rail and bei'yon'd the head of the raii, as the tread of the wheel is carried upon the Hat top of the block 5.until.the side of the wheel-flange engages the rib 6 and until the wheeLhas been forced laterally across the plate until it is nearly By reason of his construction I am enabled to employ a much lighter plate than usual, with a consequent saving in cost. Furthermore, the device for supporting the outer edge of the plate may be lighter than usual.

.The length of the device preferably somewhat exceeds the overlying distance of two ties, to which the device is secured. 7 7 are plates secured upon the tops of the ties and provided with ears or lugs8 and 9, these lugs being oppositely arranged upon the two plates. The outer lugs 8 are pro= vided with the horizontal pins 10 for the supporting-links 11', the upper ends of which are pivoted upon ears 12, provided on the outer edge and corners oi the plate 2. The pivotpins are all parallel with the rail, and when the derailer is in position above the rail the links incline toward the head of the rail, so thatpressure applied on the top of the derailee tends to hold the device against the side of the rail and against the outward-moving force of the wheel-flange when acting upon the inclined rib or shoulder 6.

The movement of the derailer toward the side of the rail is limited by the lugs 13, which depend 'from the under side of the plate 2 and plate maybe moved back and forth toward which incidentally serve as attachments for the operating device. This operating device comprises the links or arms 14, fixed upon the rock-shaft 15, that is held in and betweenthe lugs 9 on the plate 7. The rock-shaft is oper ated by the crank-arm 16, that; is connected with a-suitable operating-leveror with the adjacent switch-stand if automatic operation is wished for. The upper ends of the arms 14 are provided with the inclined slots'17, engaged with the pins 18 in the lugs 13, whereby the the rail-head. Because of the dependin-g lip or flange-4 on the plate which overhangs the rail-head it is necessary to, raise and free the end of the plate before it can be started back and thrown away from the rail. This function,is performed by the inclined slots and pins 18, it being evident that upon the first movement of the arms 16 and arms 14 the first backwardly upon the links and arms,as shown in Fig. 3, and the top of the plate drops below the head of the rail, being thus safely removed from the path of depending parts on the cars that may pass over it. When the arm 16 is again operated, it is obvious that the plate will be liftedand swung toward the rail and'strikiug the beveled corner of the rail will slip over the top thereof; The length of the slots 17 in the arm or arms 14 is such that the plate is permitted only a small vertical movement with relation to the arms 14 when the same are in an approximately vertical position. In order to permit the full backward fall of the plate and links 11, I find it desirable to elevate the centers of the shaft- 15 abo'vet-he centers of the pins 10 or else make the'arms 14 longer than the links 11.

When my device is to be used upon small track-rails, the plates 7 are sunk in the ties. It will be noted that the plate 2 has the projecting tapered end 19 and the end notch 20. These are provided to prevent the derailment of a train passing onto the siding before the derailer has been thrown out.

As numerous modifications of my invention will readily suggest themselves to one skilled in the'art, I do not confine the sameto the specific construction herein shown and described- Having thus described my invention, I
